[QUOTE="Cataceous, post: 241700, member: 38109"] The difference relative to TT seems suspect. Intra-day variation in SHBG is pretty small, and propionate is delivering testosterone pretty steadily—i.e. without large fluctuations that would appear to momentarily decouple FT from TT. Do the measurements use equilibrium dialysis? The area under the curve is going to be 50% higher at the higher dose. I'm not sure how much the apparent half life would be affected. It might not be too noticeable at these lower doses. I have only injected subQ. I have not attempted to measure both peak and trough levels in one injection cycle. However, I have accumulated a fair number of individual measurements from various cycles. Basic modeling suggested that measurements about three hours post-injection were consistent with the predicted peak for the dose. However, more recently I took measurements at five and six hours post-injection. These were also in the ball park of predicted peak levels, suggesting more of a plateau before levels begin to decline appreciably. It's plausible that pure propionate produces an earlier and sharper peak than the blend I'm using. As [USER=39921]@bixt[/USER] says, it's hard to know exactly what's going on without having hourly values. [/QUOTE]
